Hope they see these mods as a positive thing and don't become the next Astell and kern blocking the FW from future mod. I really like this mod by
@MrWalkman , seriously before his mouth d I had DMP-Z1 v 1.02 mod and liked it but felt it leaked some warmth and was getting bored of my wm1A, wanted to trade it for an AK or fiio, glad ths new mod spared my wm1A from being sold.
Wonder if MrWalkman can further tweak the firmware image to give us back, perhaps 1GB more of space by removing the demo songs that come in the Walkman (if you remove them they are not gone, I did a factory reset on my A55 and they came back!)
